Hypothesis Testing Hypothesis Testing In today’s world of statistical research there is a multitude of ways to make new discoveries and formulate new ideas; one way to accomplish this is for researchers to have inquiring minds that need to have their questions answered. To do this they must develop their hypothesis. Then researchers can develop a verbal and numerical hypothesis in which they will be able to test this hypothesis.
